Title:
ACIDIC GAS ELIMINATION DEVICE AND ACIDIC GAS ELIMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/087900
Kind Code:
A1
Abstract:
A regeneration column 14 for regenerating an acidic gas absorbing liquid is provided with a regeneration column condensing unit 40 for condensing moisture from entrained gas 41 which contains an entrained corrosive substance and acidic gas and is discharged from the top of the acidic gas regeneration column. The regeneration column condensing unit 40 is provided with a gas discharge line for discharging the entrained gas 41 from the top of the regeneration column; a cooler 42 interposed on the discharge line; a gas-liquid separator 43 for separating regeneration column condensed water 44, which is obtained by steam being condensed by the cooler, and CO2 gas; a reflux line 40b for refluxing the regeneration column condensed water 44 more to the top side of the column than a rich solution introduction unit 14a; a condensed water receiving unit 14e for storing the condensed water 44 that has been introduced by the reflux line 40b; and a first condensed water withdrawing line 14g-1, connected to a lean solution supply line 53, for withdrawing condensed water 44 from a condensed water withdrawal unit 14f in the condensed water receiving unit 14e.
